Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery and equipment, in particular to an anti-distortion linear capping machine. Background Art

[0002] The packaging of filled products usually requires the use of a capping machine. There are two types of capping machines: a screw capping machine and a press capping machine. The screw capping machine screws the cap onto the product container by rotating the screw capping head, while the press capping machine presses the cap onto the product container directly without rotating the capping head.

[0003] The capping machine is a packaging machine currently widely used in the pharmaceutical and food industries. It is suitable for the screw-on sealing process of plastic bottle caps and bottles after bottling of medicines and foods. It is an automated device with high packaging efficiency and simple and convenient operation. Among them, the linear capping machine is a machine in which the bottle body does not stop at a fixed position. The relative movement of the bottle body and the bottle cap on the conveying line is used to complete the capping. The bottle body does not stop, which is simple and efficient. In particular, for some special bottles and bottle caps, it is sometimes necessary to fix the bottle cap and rotate the bottle body to complete the capping installation. The traditional capping is that the capping wheel is driven by an ordinary motor to pre-screw and re-screw the bottle cap, which is efficient and convenient. The disadvantage is that the bottle cap is easily twisted, and the rotation force is too large or too small to adjust. Therefore, there is often a capping plate above the bottle cap to press the bottle cap for capping.

[0004] For example, the automatic capping device disclosed in publication number CN217103003U has a frame provided with: a clamping assembly for clamping the bottles on the conveyor; a pressing assembly for pressing the bottle caps; the bottle caps can be positioned, and the bottle caps are more stable when rotating and have a greater tightening force.

[0005] However, for the linear capping machine, the vertical extension and retraction of the pressing assembly of the device is not applicable, and the use of the capping wheel for the linear capping machine is easy to twist the bottle cap. Utility Model Content

[0006] The utility model aims to provide an anti-distortion linear capping machine to solve the technical problem that the existing linear capping machines are prone to distorting bottle caps.

[0007] The embodiments of the present invention are implemented by the following technical solutions:

[0008] A deflection-proof linear capping machine comprises a frame and a conveyor belt arranged on the frame, wherein bottle rubbing devices for rubbing the bottle body to rotate and cap rubbing devices for rubbing the bottle cap to rotate in the opposite direction are arranged on both sides of the conveyor belt, and a cap pressing device for pressing and fixing the bottle cap is also arranged above the cap rubbing device.

[0009] By adopting the technical scheme, the bottle body is rubbed by the bottle rubbing device, and the bottle cap is rubbed by the cap rubbing device at the same time, and the two rotate in opposite directions at the same time. For the cap rubbing machines of the same length, the rotation speed of the bottle cap is reduced accordingly to reduce the rotation speed of the bottle body, and the rubbing speed and force of the bottle cap by the cap rubbing device are reduced accordingly, thereby reducing the possibility of the bottle cap being rubbed crooked or falling off. At the same time, a cap pressing device is installed above the bottle cap to prevent the bottle cap from being screwed out, falling off or screwed crooked.

[0010] Preferably, the bottle rubbing device comprises a bottle rubbing rack for adjusting the spacing to adapt to the radius of the bottle body, and the bottle rubbing rack is slidably arranged on the frame.

[0011] By adopting the technical solution, the bottle rubbing device is slidably arranged by the bottle rubbing frame and can be adjusted according to different bottle bodies.

[0012] Preferably, the bottle rubbing device further comprises a first bottle rubbing belt and a second bottle rubbing belt which are arranged in parallel on opposite sides of the bottle rubbing frame, and the first bottle rubbing belt and the second bottle rubbing belt rotate in opposite directions.

[0013] By adopting the technical solution, two groups of bottle rubbing belts are arranged in parallel to disperse the pressure of the bottle rubbing belts on the bottle body, so that the bottle body can be rubbed more evenly.

[0014] Preferably, the first bottle rubbing belt and the second bottle rubbing belt are drivingly connected to the same transmission shaft.

[0015] By adopting the technical solution, the two groups of bottle rubbing belts rub synchronously, and the force magnitude and rotation direction of the bottle body are consistent.

[0016] Preferably, the bottle rubbing rack is further provided with a connecting frame connected to the frame.

[0017] Preferably, the cap rubbing device comprises a cap rubbing frame slidably arranged on the bottle rubbing frame and a cap rubbing belt arranged on the cap rubbing frame, and the cap rubbing frame is used to adjust the spacing to adapt to the radius of the bottle caps.

[0018] By adopting the technical solution, the cap rolling rack can be adjusted according to different bottle caps to adapt to bottle caps of different sizes.

[0019] Preferably, the capping device comprises a capping frame telescopically arranged on the top of the frame and a capping belt arranged on the capping frame.

[0020] By adopting the technical solution, the capping frame can be telescopically adjusted to adapt to the heights of bottles with different bodies.

[0021] Preferably, the rotation direction of the capping belt is opposite to that of the conveyor belt, and the rotation speeds are equal.

[0022] By adopting the technical solution, the capping belt moves closely to the bottle cap and has the same speed as the bottle cap in the moving direction, and will not produce relative displacement with the bottle cap, thereby preventing the cap from being distorted.

[0023] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0024] 1. The utility model rubs the bottle body through the bottle rubbing device, and rubs the bottle cap through the cap rubbing device at the same time. The two rotate in opposite directions at the same time. For the cap rubbing machine of the same length, the rotation speed of the bottle cap is reduced by the rotation speed of the bottle body, and the rubbing speed and strength of the cap rubbing device on the bottle cap are reduced accordingly, thereby reducing the possibility of the bottle cap being rubbed crooked or falling off;

[0025] 2. The utility model installs a capping device above the bottle cap to prevent the bottle cap from being screwed out, falling off or twisting;

[0026] 3. The utility model can be adjusted to suit different bottle bodies and bottle cap sizes. BRIEF DESCRIPTION OF THE DRAWINGS
